Well since a FOB felt like kissing my sister I am fletching blazers
I am putting one hell ofhelico on them

So what is the advantage of more helico? Accuracy is what I think, more spin.

That is correct, more spin. I would say, though....that w/ blazers....offset works quite well too. Now, I do fletch mine on a helix, and it SEEMS to make a difference.

You misposted.[8D] I offset mine, I do not helical them. (tho highly recommended). I use a straight clamp and offset them as hard as the size of the arrow allows me while still getting contact.

Think of it like rifling in a barrel, Germ... the twist spins the bullet to stabilize it in flight and help it to not "knuckleball" through the air... Compare a smoothbore throwing a slug 150 yards to a dedicated slug gun with rifling shooting Sabots.

Same concept.

what is a fob?

Different lengths/weights of bullets stabilize better at different rates of twist from rifle barrels, I wonder if different lengths/weights of arrows would stabilize better or worse at different rates of offset or helical?

I have always felt that the additional air resistance the fletching imparts at the rear of the arrow was at least as important as the rotational spin. Harder offset or helical = more air resistance.

I'm sure you're right, Roskoe... the spin would help diminish a broadhead blade wanting to "plane" and steer the arrow off in another direction (much like a paper airplane will do when it catches a bit of wind after it's thrown), and the "drag" on the back end serves to facilitate that, I'm sure.

How much speed would I gain switching from 4" Vanes to blazers? Is this more about accuracy instead?
Thanks Gents,
